I mean damn, did you even see the test?

The way Kanye talks about college life so many times in his songs is why they are very easy to relate to. He questions why he should feel so impressed with himself when he did so poorly on his last test.

The line is also a double entendre:

Literally did you “see” the test.

But also did you even “C” the test?

The grading system in many countries works from A(*) to E. Getting a “C” or above is sometimes considered a ‘higher-grade pass’; so the bare minimum to get a ‘good’ job is a “C”. This leads nicely into the next line, where he gets “Ds” — the grade below “C”.
